While I've my editors hat on, some items in the article grated on this reader.

"I count over 200 references to this document with my website along." Should this read: I count over 200 references to this document [with]IN my website alonE?

Also, while host to host Ethernet cables are "crossover", host to host Serial Cables are typically called "null modem".

One more item, if you rsh into the first box, then tip in to the second, a ~. will kill your rsh, not the tip. Use ~~. to kill the tip. I almost always forget this one at work. Not sure how ssh will behave.

The article suggests using two null-modem cables, one from sio0 on box A connecting to sio1 on box B, and the other one connecting sio1 on box A to sio0 on box B. Would it not be possible to use just one cable and connect sio0 on A to sio0 on B?
